MC33880

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33880/D Rev 3.0, 01/2004 Advance Information Configurable Octal Serial Switch with Serial Peripheral Interface I/O The 33880 device is an eight-output hardware configurable high-side/lowside switch with 8-bit serial input control. Two of the outputs may be controlled directly via microprocessor for PWM applications. The 33880 incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The 33880 controls various inductive or incandescent loads by directly interfacing with a microcontroller. The circuit’s innovative monitoring and protection features include very low standby currents, cascade fault reporting, output-specific diagnostics, and independent shutdown of output. Features Designed to Operate 5.5 V < VPWR < 24.5 V 8-Bit SPI for Control and Fault Reporting, 3.3 V/5.0 V Compatible Outputs Are Current Limited (0.8 A to 2.0 A) to Drive Incandescent Lamps Output Voltage Clamp Is +45 V (Typical) (Low-Side Drive) and -20 V (Typical) (High-Side Drive) During Inductive Switching Internal Reverse Battery Protection on VPWR Loss of Ground or Supply Will Not Energize Loads or Damage IC Maximum 5.0 µA IPWR Standby Current at 13 V VPWR up to 95°C RDS(ON) of 0.55 Ω at 25°C Typical Short Circuit Detect and Current Limit with Automatic Retry Independent Overtemperature Protection 32-Pin SOIC Has Pins 8, 9, 24, and 25 Grounded ...
